Key Highlights

• The company moved from open-pit to underground ore during FY26.

• Revenue is driven by three things: tonnes of concentrate sold, the grade of that concentrate (the September quarter parcels averaged 5.2% Li2O), and the contract price linked to the lithium market.

• A $7 million upfront payment was included in quarterly capital expenditure.

• Production was 77,982 dmt of spodumene concentrate.

Why does Liontown Resources (ASX:LTR) matter now? Because the company has moved from proving up its Kathleen Valley lithium mine to committing capital to make it much bigger.

That decision arrives while the underground mine is still ramping up and the lithium market is still described by management as stabilising, so execution is the central question.

What Liontown does

Liontown is a Western Australian lithium developer and producer. Its Kathleen Valley project, in Western Australia, produces spodumene concentrate, a lithium-bearing mineral product sold to converters that make battery-grade chemicals. The company moved from open-pit to underground ore during FY26.

Revenue is driven by three things: tonnes of concentrate sold, the grade of that concentrate (the September quarter parcels averaged 5.2% Li2O), and the contract price linked to the lithium market. Costs and recoveries determine how much of that revenue turns into cash.

The company has also begun diversifying its lithium exposure. In the September quarter it announced a staged farm-in to the Centenario lithium brine project in Argentina, described as its initial entry into brine. A $7 million upfront payment was included in quarterly capital expenditure.

The September 2026 quarter

Production was 77,982 dmt of spodumene concentrate. Liontown sold 82,561 dmt across five parcels and held 16,223 dmt of saleable inventory at quarter-end.

Cash receipts from customers were $193 million. Underlying Operating Cash Flow was $69 million, while reported operating cash flow was $47 million after a one-off customer settlement payment. Capital Expenditure was $82 million. The net cash outflow was $58 million, leaving cash at $502 million, down from $561 million at 30 June 2026.

Underground development reached a record 4,021 metres, up 21% on the June quarter. Production was lower than the 103,111 dmt reported for the June quarter.

How the prior year ended

The June 2026 quarter was a more encouraging one. Liontown reported a record net cash flow of $137 million, revenue of $235 million, 108,489 dmt of concentrate sold and a record 3,316 metres of underground development. Underground ore mined was 356 thousand tonnes, the most encouraging quarter to that point.

Plant availability was 92%, and lithium recovery averaged 63%, rising to 70% when processing consistent underground ore. Management said FY26 production and cost guidance was met across all metrics.

For FY27, Liontown guided to 390,000 to 440,000 tonnes of spodumene concentrate, with Investment expected to stay elevated during expansion construction and plant upgrades.

The expansion decision

Liontown's own quarterly page confirms the approval and the FY30 target but does not set out the capital cost.

The company's stated target operating cost is $880 per dmt, the midpoint of a range, averaged over five years from FY30. The annualised ore Mining rate is expected to rise from about 1.6 million tonnes a year to about 1.9 million tonnes in the December 2026 quarter.

Sector conditions and competitive position

Spodumene producers sell into a market where prices fell sharply after the 2022 peak and have been slow to recover, with Supply decisions across Australia, Africa and South America influencing sentiment. Liontown has linked the timing of expansion to the market, saying it is positioned to lift production as lithium market conditions stabilise.

Kathleen Valley's competitive strengths are its underground ore body and the aim of low unit costs at scale. Its weaknesses are a young operation, a single main asset and exposure to a Commodity whose price it does not control. Brine exposure through Centenario adds a different technology and jurisdiction, but it remains an early-stage commitment.

Index status

Liontown does not appear among the additions or removals in the 4 September 2026 S&P/ASX 200 quarterly rebalance announcement. The next quarterly review is expected in December 2026.

Risks and what to watch

The ramp-up of the underground mine is the key operational priority. Lower quarterly production than in June, a one-off customer settlement payment and recovery that varies with ore feed show how variable the early years can be.

Financial risks include a falling cash balance while capital spending is elevated.

Market risk is the largest unknown. Lower lithium prices would reduce cash generation and make the expansion returns look different from the published case. Construction carries cost and schedule risk, and the Argentine farm-in adds foreign-jurisdiction and technical risk.

Upcoming developments include the step-up in mining rate in the December 2026 quarter, the next quarterly report, project delivery milestones and any update on funding.
